the car has smelled like gas from the minute i received it. the previous owner told me that mercedes had quoted 5 grand to fix it so i would only put half a tank in at a time. turns out there was a warranty on it but has since expired. why wasn't it fixed for free when the previous owner brought it? this is very dangerous and can cause an explosion. the warranty should have been fixed rather than quoted and seems very greedy to not disclose that information but instead giving a quote. i have lung and heart problems and this is a definite safety issue that needs to be corrected regardless of the age of the car also brought it to dealership scared and they told me too bad it's been too long. how is a gas leak an ok thing to dismiss?????? i have been trying to get this fixed for years and this is my 2nd attempt for a recall with no response at all

I starting smelling a gassy smell seeping into my house at night and after a few days concluded in had to be coming from the attached garage and subsequently after eliminating all other variables I narrowed it down to the car. I parked it outside for a couple of nights and the smell ceased in the house and garage. I then took the vehicle to pompano mercedes to have them check it out and was informed my seals were bad/leaking at the fuel line connections, so without a choice I had them repaired at a cost of $968.21 on 9/13/2010. This resolved the problem for about 2 months, then the gassy smell returned. I took the car back to pompano mercedes again and explained that I had the car had the same symptoms of a gassy smell. They checked out the vehicle and informed me at this time I had a different fuel leak and that would require them to replace the entire gas tank and internal fuel pumps and seals at a cost of $3000 this time. Quite unhappy with this diagnosis considering I was just there 2 months prior and thought they had repaired the problem only to find out now it was more encompassing than their first attempt at a fix and it was going to cost a boatload of money to re-repair the problem as I was just over the 50k warranty to boot. With the news of the extended warranty settlement at this time I strongly feel my vehicle issues are as described in the class action suit and I should be entitled to reimbursement for the $968.21 I spent at mercedes discretion.

After filling the gas tank, I parked the car in my attached garage the next day the gas fumes were so strong inside my basement that I called my plumber, thinking I had a gas leak from the furnace. Then I went into my garage, and the gas smell was overwhelming. When I took the vehicle to mercedes benz, they did a diagnostic and determined the fuel sensor was bad, along with cracked inner tank module. I had to replace all the associated parts (cable harness, auxiliary pump, bracket, seal ring, etc. Parts: $710.13 and labor: $496.80 = 1206.93. This issue should be reviewed as a manufacturer defect. I've had many automobiles, and never did I have this headache. And I certainly would not expect this from this car. Mercedes benz needs to own up to these defaults!!! Additionally, my battery died at the same time - another parts: $284.05, labor: $207.00.

I have a fuel leak on the left side of my fuel tank. The fumes are so strong that I cannot operate the vehicle due the amount of fuel that settles on top of the pump/ regulator access outlet. The stream is emitting from the area of leakage so quickly that it takes about a minute to puddle and drip to the ground. The danger of a metal object being picked up by a tire and caught up on a piece of metal under my vehicle, at that location, would create a spark that would surely cause a blazing fire to erupt. Also, there is the danger of a passerby tossing a cigarette out of his/ her window, being caught up by the wind and sucked underneath my car, causing a fire.

I filled up my car & noticed a gas smell I was on my way to atlanta for work I had to inhale strong gas fumes for most of my travel. When I got there I took my car to a shop & they discovered my gas tank had a leak and gas was leaking near back seat they gave a me an estimate of about 2500 to fix I was told that this had been a known issue for mercedes but no recall yet which I don't understand. This is very dangerous not only the inhalation of the fumes & gas leaking in a car with electrical wiring & parts that get extremely hot. I don't understand why there hasn't been a recall to fix this since mercedes are aware that the car was manufactured properly. Why should we have to pay to repair poor manufactured products that put our lives in danger.

The fuel tank cannot be filled up completely. Doing so causes the car to smell like gasoline. There seems to be a fuel leak on the tank which causes the gasoline to spill. The odor comes mostly from the back seat of the car. If the tank is filled, the car will have the gasoline odor for weeks even with the windows left open. This is quite dangerous in many ways since I have an infant who is required by law to sit in the backseat rear faced.

There was a fuel leak that caused the car to smell of gas when the tank is near full (3/4) to completely filled. The fuel has not been leaking to the ground and I have been unable to pinpoint exact location. When I would go into my closed garage after the car had been parked for a while the smell of fuel is too strong to ignore. My mechanic told me the source is the sending unit and tank assembly. He told me the failure was common and the situation could become very dangerous if ignored. The cost to replace the tank is going to run $2,000. The car has never been damaged and should not require a tank replacement at this point in its lifecycle.
